In Design: Rolling Road Widening and Old Keene Mill Road Intersection Improvements in Fairfax County

Old Keene Mill Road Intersection Improvements

This project (completed in November 2021):

• Added a second left-turn lane from northbound Rolling Road (Route 638) to westbound Old Keene Mill Road (Route 644)
• Added a dedicated right-turn lane from northbound Rolling Road to eastbound Old Keene Mill Road
• Striped four higher-visibility crosswalks
• Replaced pedestrian signals with ones that are Americans with Disabilities Act (ADA) compliant and accessible
• Replaced the traffic signal to accommodate the new turn lanes
• Reconstructed the median along Rolling Road just south of Old Keene Mill Road

At the intersection, Rolling Road averages about 25,000 vehicles a day and Old Keene Mill Road averages about 35,000 based on 2019 data.

Rolling Road Widening 

Plans include:

• Widening Rolling Road from two to four lanes between Viola Street and Old Keene Mill Road
• Traffic signal upgrades 
• A shared-use path for bicyclists and pedestrians
• Access management improvements 

The project team has worked with Fairfax County to consider alternative design options, including the possibility of undergrounding utilities. This option was evaluated based on feasibility, potential property impacts, cost and schedule. This is no longer being pursued due to cost.

Within the widening project limits, Rolling Road averages about 21,000 vehicles a day based on 2019 data.
